Application i'led December 22, 191'?. Serial No. 208,410.

To all whom 'it may concern: p Be it known that I, JOHN A. PrnoHER, a citizen ot the United States, residing at Roanoke, in the county oli' Roanoke and State of Virginia, have invented certain new and useful Improvements in Car-Truck Side Frames, of which the following is a specilication.

This invention relates to car truck side frames of the arch bar type and has for its object to provide improvements in the construction of such devices whereby metal may be saved and whereby the metal used may be employed to better advantage. The invention consists of the formation, coin-bination and arrangement of parts as will be herein described and claimed.

ln the drawings, Figure 1 is a broken plan view of a side trame constructed in aecordance` with the present invention and Fig. 2 a similar side elevational view of the same. Fig. 3 is a horizontal section thereof taken substantially on theliiie 3-3 of Fig. 2. Fig. il is a fragmentary section taken on the line -l-l oli Fig. 1. Fig. 5 is a vertical section taken on the line 3*5 ofFig. Q.

Referring now to these drawings, the side frame consists of a top arch member 1 and a bottom arch member 2, these being vertically spacedl apart at their centers with a spring seat member 3 resting upon the bottom arch member and vertical columns or ties e located intermediatethe ends of the frame and in spaced relation to each other longitudinally of the frame, thereby providing a window opening therebetween. These ties extend upward to the top arch melnber and are secured thereto. The outer ends of the arch members converge and are coactingly secured together to form a truss, the oil boxes, such as 5, being secured to the ends of the Jiframes. A spring plank 6 of the customary construction may be used to form a crosstie member for spacing the frames when used on opposite sides of a truck, one of the features of the invention being the manner of lconnecting a spring plank of such or other construction to the spring seat member 3. y

For co-actingly securing the ends ofl the arch members together, the top member which ismade of a structural channel, with the web horizontal and the iianges depending, is of less length than thebottom member, and the bottom arch member, which is made of a steel baigpasses, near the ends of the top arch member, between the flanges of the channel and against the lower face of its web. Just beyond the end of the channel .the metal of the bottom arch member is upset or distorted at 7 to form an abutment or seat for the end metal of the channel, the upset being both for the flanges and for the web. The original cross section of the metal of the bottom arch vmember is then carried on outward at 8 to form a part of the securing means l'or the journal box 5 which is attached to the side frame by means of the longitudinally spaced, vertical box bolts 9. These bolts are disposed one to either side of the upset metal 7, the outer bolt passing through the bottom arch member only and the inner one through both arch members.

The spring seat member 3 is made of pressed steel and includes a transverse bot tom bearing face 10 shaped to conform to and bear upon the central upper face of. the bottom' arch member. `From this bottom, substantially vertical side walls or flanges 11 rise and the central portions 12 of these flanges are llared and flattened away from each other to form a flat spring seat. A spring plank such as 6 or its equivalent is riveted to these portions 12 and thus forms4 a tie across the open `space between the two side walls and these iat portions.

The side walls 11 at their ends extend upward in vertical planes and inserted between them arethe lower endsof the columns i. These columns are made of flanged or channel sections, the backs oi the webs being turned toward each other and there being rivets passing through the upstanding flanges ol the spring plank channel and the vertical webs of these columns. Securing rivets also pass through the side walls 11 of the'l spring Aseat member and the lower ends of the flanges of the columns, thus forming not only vertical strength but also transverse strength.` Each part thus serves to stay and brace the other and is at the same time of light weight. At their upper ends the webs of the columns at 13 are bent at right angles away from each other to abut andunderlie the bottom face of the top arch member. At the sam'e time the side flanges at 14 are carried upward and bent around over the back,

of the top` arch member. Securing rivets then pass through the top arch member and through the underlying and the overlying portions of the columns. A V p Secured to the adjacent inner faces of the columns are `vertical wear plates'l'which,

at their upper ends are likewise bent to form knees to lit under the top arch member and are then riveted thereto, thus forming a substantial tie at the top. As the top and bottom arch members are preferably made of different widths, so the columns are similarly tapered from the top to the bottom.

I have thus described an embodiment of my invention. @ther embodiments are possible within the scope of the appended claims without departing from the spirit of the invention.

I claim:
